" SIPHON-SKIMMEE. i

Specification of Letters Patent.-

Patented'Nov. 26. 1 907'.

To: all whom it may con-cam:

.Bert known that I, (JURris HARBERT, a citlzenof the United States ofAmerica,- residing at Smethport, in the county of McKean and State ofPennsylvania, have invented new and useful improvements 111Siphon-Skimmers, of which the f llowing is a specification.

My invention relates to a device for removing cream from milkreceptacles in such a manner as to draw oil the layer ol' cream withoutdisturbing the underlying bod-y ol milk.

W object of the invention is to provide a simpleand eilectiveconstruction of siphon skimmer, whereby the operation of with drawingthe cream may be conveniently performed. Another object is to provide asiphon having, means for controlling the flow of the current'of cream.

A still further object is to provide a gage for. indicating the depthtowhich the siphon shculdbe' introduced into the bottle or container forthe complete withdrawal of the layer of cream.

In the accompanying draw1ngs,-F1gure 1 'is a sectional view of a milkbottle showing the application of the invention thereto. Fig. 2 is asectional view of the siphon skimmer.

Referring to the drawings, 1 designates a milk receptacle, shown in thepresent instance in the arm of a bottle of ordinary form and standardsize to contain, say, a quart of milk; 2 designates a body of milkwithin the bottle; and 3, the superposed layer of cream which has risenfrom the, milk.

In carrying my invention into practice I provide means for su portingthe skimmer upon the neck of a. ottle, the supporting means shown in thepresent instance comprising a cap 4 adapted to rest upon and engagetherim of the bottle neck. This cap is provided with a tubular guide sleeve5 conforming in diameter to the short leg of the siphon 6. The saidshort leg 7 of the siphon comprises a tube open at each end and provided at its lowerv end with a scale 8 having graduations in inches withdesignating numerals extending upwardly in regular order from the lowerend thereof. This gage may be of any suitable length and is provided toenable the leg 7 to be inserted a required depth in the bottle in aneasy and conven within the leg 7 and is similarly provided with a stem15 carrying at its upper end a knob or finger iece 16. The lower end ofthe plunger 1 1 1S curved, as shown at 17, so that when drawn up -to itsfullest extent it will conform to the arc of curvature of the upper wallof the part 10, to guide the discharging column of cream thereinto.

Suitably attached to the supporting cap 4 is a gage strip 18, preferablyconsisting of a section of metallic tape bearing an inch scale arrangedin a reverse order to the scale upon the leg 7 of the si hon, namely,with the designating numeral; thereon extending downwardly instead ofupwardly.

In 0 oration, the device is applied to the bottle in the manner shown inFig. -1,.the cap being first inserted into position and the gage 18allowed to depend on one side of the bottle. By reference to this gage18 the operator may determine from exterior visual observation theextent to which the leg 7 should be inserted in the bottle to bring thelower end thereof down to the bottom of the layer of cream 3. presentinstance that the numeral12 011 the scale 18 registers with the line ofdemarkation between the body of milk and layer of cream, thus indicatingthat the leg 7 should be inserted to the depth of twelve inches. The leg7 is passed through the guide sleeve 5 in the cap and forced downwarduntil the scale line 12 thereon registers substantially with the uppersurface of the cap, the siphon being supported by the frictionalengagement between the leg 7 and wall of the sleeve 5. After the partshave been applied, the plunger 14 is drawn upwardly until it occupiesthe position shown in Fig. 2, thus forming a partial vacuum in thesiphon, which causes the cream to flow upward in the leg 7 untilcommunication is established with elbow 10, so that the column of creamwill discharge through leg 9 as soon as the stopper 11 is withdrawntherefrom.

It will thus be seen that my invention provides a convenient and simpleform of device by which thed'siyer of cream arising from the milk in abottle may be conven:

A corresponding plunger 14 is arran ed It will be observed .in theiently withdrawn without withdrawing any of the milk, and by which theshort leg of the siphon skimmer may be accurately adjusted to draw offthe cream.

Having thus described the invention, what is claimed as new, is

1. A siphon skimmer attachment for milk bottles comprising a supportingmember for closing the mouth of the bottle, said member being providedwith a guide sleeve, a siphon having its intake leg slidably mounted insaid sleeve and provided with a scale having designating numeralsextending in increasing valuation upwardly from the lower end thereoffor coaction with a portion of said supporting member, and an indicatingstrip carried by said su porting member and projecting downwar' at oneside thereof to depend'upon thee; terior of the bottle, said strip beingprovided with a cooperating scale having its designating numeralsextending downwardly thereon.

' 2. A siphon skimmer attachment for milk bottles comprising asupporting member adapted to engage the mouth of the bottle, a siphonhavingits intake leg slidably mountedun said supporting member andprovided with a gage com rising a set of designating numerals eXten ingupwardly thereon for coaction with said supporting member, and a gagestrip carried by the sup orting member and projecting downwar atone sidethereof to depend upon the exterior of the .bottle, said gage beingprovided with a cooperating set of designating numerals extendingdownwardly thereon.

. 3. A siphon skimmer attachment for milk bottles comprising'a flangedcap adapted to the cap and projecting downward at one side thereof todepend therefrom upon the exterior of the bottle, said strip beingprovided with a coeperating set of graduations and designating numeralsextending downwardly in increasing valuation.

4-. A siphon skimmer attachment for milk bottles comprising a flangedcap having a central guide sleeve, a siphon having a short leg open atboth ends and slidably mounted in said sleeve, and a long leg connectedat I its upper end with said short leg below the upper end of thelatter, the lower portion of the short legof the siphon being providedwith'ascale having numerals extending upwardly thereon for-coaction witha portion of the cap, stoppers slidably mounted in the legs of thesiphon, and a gage strip connected at its upper end with the cap anddepending at one side therefrom to project down upon the'ontside of thebottle, the numerals upon said strip being arranged in reverse order tothe numerals of scale on the siphon. I

In testimony whereof, I affix my signature in presence of two witnesses.
